Frozen water could be turned into ice and blended at will, "ice blended". But what amazes us is to see that soda has similar effects.
Warning: Leaving soda in the freezer too long can result in the container bursting and leaking, and a real big mess. Glass bottles are not recommended, as the ice expands when freezing and can shatter the glass explosively. Use of video content is at viewer's own risk.
The anomaly of "self freezing soda" has been observed by many people, usually by accident when we forget that we left a soda in the freezer, still liquid and tries to open it.
To get this effect, I shook up and put 4 bottles of 500mL (16.9 oz) soda in a freezer set at -24ºC (-11ºF) between 3¼ to 4 hours. The longer they're in, the more dramatic and solid the slushy freeze will be. However, anytime longer than 3 hours and 15 minutes, there's a chance of them freezing before you take them out.
Shaking the up increases the pressure in the bottle, and actually lowers the freezing point a little.
Every freezer will be a little different temperature, and I've noticed the location of your bottles in the freezer makes a dramatic difference on freeze times. For best results, choose one consistent location in your freezer, and play around with freeze times to see what works best for you. In my freezer, the middle of the center rack settles at -24ºC (-11ºF) and takes 3:15 to super chill 4 bottles.
Remember to keep the freezer door closed. More frozen items in your freezer will help your soda chill faster. The bottom line is to use a consistent environment to obtain consistent results!
The trick to getting the 3-second slush, is quickly releasing the pressure in the bottle and re-securing the cap, flipping the bottle upside down, and back upright again. This is because the forming ice crystals will be moved around the length of the bottle, and trigger nucleation for the rest of the soda.
If you were to just take the cap off, ice will form, and it will slowly spread downward, but might take upwards of 2 minutes for the bottle to completely freeze.
Once you've iced your soda, try pouring it into a glass to see how slushy it really is. It should have a consistency similar to that of a Slurpee.
It's actually the water that is forming the ice crystals, and you'll notice the ice will begin to float to the top, trapping some of the soda syrup, and making for a delicious carbonated ice slush.
If you were to remove the ice, the rest of the syrup would be more concentrated due to all the water that was taken out from it.
I found that if you opened the cap just enough to hear the bottle hissing, and held it there until it stopped, you could remove the cap completely and the soda would stay a liquid.
I put a metal bowl in the freezer for about 30 minutes, and when it came out, it got frosty from the moisture in the air. If you pour your supercooled soda into a frosty bowl, it's enough of a nucleation point to trip the ice crystallization, and you'll be able to pour yourself and "instant slushy".
Some people have asked what would happen if you were to drink a supercooled soda. Simple answer is that it's cool and refreshing!
As the soda ices, latent heat is released in the crystallization, and it actually warms up to just below freezing. That's similar to just having a drink with ice cubes floating in it, so go ahead and enjoy it!
If you try pouring your supercooled soda into a regular clean bowl, or glass, it will just look like regular soda.
Now drop a flake of ice, or ice cube into the liquid.
As if by magic, the soda will crystalize until the whole bowl becomes slush.
This also works with cans of soda as well, but it is tougher. The freeze time is about the same, and the key to making it work is releasing the pressure from the can very very slowly. This is much harder to do that opening a tab, but it is possible, and the soda has the same properties as the stuff from the bottles.
Obviously?
I also experimented with 2 litter bottles, and had great results freezing them between 4-5 hours. The whole bottle slushifies in an instant if you shake it upside down for a second.
Experiments with Gatorade, Fresca, Mexican Sprite, Rootbeer, Orange sodas, Coke, Diet Coke, in bottle form, as well as in cans resulted "super cooled" success too!
Removing the pressure very slowly from the bottle, will keep the soda liquified, and give you the opportunity to play with supercooled soda outside of the bottle.That's how to freeze soda instantly.
For non soda drinkers, you can do this same trick with water! Have a good time!
